【摘要】 随着互联网技术及应用的不断发展,互联网在为用户提供大量信息的同时,也为检索特定的信息带来了极大的不便。由于传统的检索都是用关键字来进行的,由于自然语言的歧义性,一个关键字可以出现在多个不同的信息领域中,并有不同的意义,因而在检索时会很难查到用户真正需要的信息,查准率、查全率都不能令人满意。利用本体建模的方法,对服装领域的知识表示和描述以及为服装领域知识检索、提高检索的查准率和查全率成为一个值得研究的课题。本文主要研究基于本体的服装领域知识表示及其本体建模技术与方法,通过分析服装领域知识表示的特点,运用领域本体在知识表示方面的优势,给出了服装领域知识表示的本体模型,以及建立服装领域知识表示的本体模型的实现步骤与方法。根据当前常用的“七步法”进行服装本体的应用研究,描述了使用本体编辑工具protege3.3.1构建服装知识本体的实现过程；最后通过一个语义检索测试系统,证明了构建的服装知识表示的本体模型的可行性,并给出了服装领域的知识检索的查全率和查准率的相关测试与验证。更多还原

【Abstract】 Internet provides a lot of information for users with the continuous development of network technology and its application, but it also brings great inconvenience in retrieving specific information. The traditional searching technology is mainly based on keywords, due to the ambiguity of natural language, which makes the same keyword can appear in many different areas and have different means, and therefore it will be difficult to find the needed information for users. And we can say the precision ratio and recall ratio are not satisfying.How to use Ontology modeling method to represent and describe knowledge in clothing area in order to increase the precision ratio and the recall ratio becomes a very valuable topic worthy of study.This paper mainly studies the knowledge representation in clothing area based on ontology and the ontology modeling method and technology, and by analyzing the characteristic features of the knowledge representation in clothing area, making use of the advantages of ontology technology in the area of the knowledge representation, and then gives a ontology model of the knowledge. representation in clothing area, and gives the implementation procedure and implementation method.This paper describes the implementation procedure of how to using the editor tool proteg e3.3.1 to construct the clothing ontology knowledge according to the current frequently-used "seven-step method" to study how to apply the clothing ontology. At last, this paper proves that construction of the clothing knowledge ontology model is feasible using a semantic retrieval test system, and gives the related test and verification of the precision ratio and recall ratio of knowledge retrieving in the clothing area.更多还原
